Description
Technical field
The present invention relates to the migrating technology of user between communication network, particularly a kind of with the implementation method of user from GSM network smooth migration to the WCDMA network.
Background technology
What now, most of existing mobile operator used is the GSM network.These operators when building the WCDMA network, a major issue that solve be exactly how with the user smoothly from the GSM network migration to the WCDMA network, keep Subscriber Number constant simultaneously.Have only the constant smooth migration of the Subscriber Number of maintenance, can guarantee the success of WCDMA network development.
The scheme the user is smoothly from the GSM network migration to the WCDMA network that realizes at present has two kinds:
Prior art scheme one:
Consult Fig. 1, this scheme is called upgrading scheme.Because the function status of the attaching position register in the attaching position register (HLR) in the GSM network and the WCDMA network is similar, solution user smoothly one of scheme from the GSM network migration to the WCDMA network upgrades to the existing attaching position register of GSM network exactly, supports GSM user and WCDMA user simultaneously.Attaching position register after GSM network and the shared upgrading of WCDMA network.A user is moved to the WCDMA network from the GSM network, only need to change SIM card, revise the user type in the attaching position register, modification user's authorization data.
Though this scheme can realize that also the user moves, and exists following shortcoming:
1, to existing all the HLR upgradings of GSM network, quantities is big;
2, influence is staggered in the GSM network networking complexity easily to the planning of WCDMA network with the WCDMA network;
3, easily the existing producer of GSM network is formed dependence, be unfavorable for the buying commercial affairs of the WCDMA network equipment.
The technical scheme of prior art two:
Consult Fig. 2, the professional route register of this scheme utilization SRR writes down active user's professional routing iinformation, is called professional route register scheme.The mobile services switching centre MSC of GSM network and the MSC in the WCDMA network send among the professional route register SRR service request from user, by the routing iinformation of professional route register SRR, this request is sent to the Home Location Register of GSM network or the Home Location Register of WCDMA network according to this current user.As user during from the GSM network migration to the WCDMA network, only need the user data among the deletion GSM HLR, increase the user data among the WCDMA HLR, and revise the routing iinformation of SRR server this user.
Though scheme two also can realize user's migration, has following deficiency:
1, needs to adjust the existing route addressing mode of GSM network, need all requests to HLR are sent to professional route register SRR;
2, the GSM network is staggered in the WCDMA network, the networking complexity;
3, professional route register is used seldom on existing network, and all service request need be passed through professional route register SRR in the scheme, and risk is bigger.
Summary of the invention
The object of the present invention is to provide a kind of with the method for user, to reduce adjustment to existing network from GSM network smooth migration to the WCDMA network.
The present invention includes step:
The storage migrated users is in the related service data of this network existing business in the attaching position register of GSM network, and this user of storage is at the related service data of the existing business of this WCDMA network and GSM network and the user SIM card identification number at the GSM network in the attaching position register of WCDMA network;
Make Subscriber Number and SIM card identification number routing addressing in WCDMA network the attaching position register that respectively point to described GSM network and WCDMA network of migrated users in the GSM network;
When migrated users is initiated location update operations, be current position information with the updating location information of this user in the attaching position register of WCDMA network and GSM network, to serve this user.
According to above-mentioned technical scheme:
When revising the user service data of migrated users by OSS, the user data of this migrated users in GSM network home location register and WCDMA network home location register will be revised simultaneously at GSM network and WCDMA Web-compatible.
When revising the dedicated service data of migrated users at the WCDMA network by OSS, then OSS is only revised the user data of this user in the attaching position register of WCDMA network.
The GSM network home location register at migrated users place receives after the data modification of OSS, no longer these data is inserted into the mobile services switching centre at this current place of migrated users.
The WCDMA network home location register at migrated users place receives after the business datum modification of utilization back-up system, these data is inserted into the mobile services switching centre at this current place of migrated users.
The position of migrated users is upgraded and is comprised step:
A, the current affiliated mobile services switching centre of migrated users are initiated the location update operations request according to the routing iinformation of the SIM card identification number of this user in the WCDMA network to the attaching position register of its place WCDMA network;
The attaching position register of B, described WCDMA network simulation mobile services switching centre and according to the routing iinformation of the SIM card identification number in user's the GSM network is initiated location update operations to the attaching position register of migrated users place GSM network;
The attaching position register completing place information updating of C, GSM network;
The mobile services switching centre of the attaching position register of D, WCDMA network under migrated users is current initiated data and inserted operation requests, and this mobile services switching centre is finished data and inserted operation and return response message;
The attaching position register completing place information updating of E, WCDMA network and the mobile services switching centre under migrated users is current return response message, and upgrade the mobile services switching centre transmission canceling position request message at preceding place to this time of migrated users.
Wherein step C comprises step:
The attaching position register of C1, GSM network sends the insertion request of data to the attaching position register of WCDMA network;
Direct attaching position register to the GSM network returned response message after the attaching position register of C2, WCDMA network received described request;
The attaching position register of C3, GSM network receives completing place information updating behind the response message, and to the attaching position register home position update request response message of WCDMA network.
Among the step B, the location parameter of the attaching position register of WCDMA network in the position requests that GSM network home location register is initiated is the attaching position register number of mobile services switching centre number, VLR Visitor Location Register number and WCDMA network.
Among the step B, the location parameter that the attaching position register of WCDMA network sends to GSM network home location register also can be the attaching position register number of WCDMA network, then when migrated users during as destination, GSM network home location register is got the routing iinformation that migrated users is obtained in the roaming number request by sending to WCDMA network home location register.
Existing design does not require to the GSM network in the present invention, and quantities is little, does not need to revise the existing addressing system of GSM network.Networking structure from technical scheme it can also be seen that WCDMA network and GSM socket are clear, helps the planning and the management of WCDMA network.

Embodiment
For convenience, to hereinafter to be referred as arranging:
Gateway exchange in the GSM network: abbreviate GSM-GMSC as;
Attaching position register in the GSM network: abbreviate GSM-HLR as;
Mobile services switching centre in the GSM network: abbreviate GSM-MSC as;
Attaching position register in the WCDMA network: abbreviate WCDMA-HLR as;
Mobile services switching centre in the WCDMA network: abbreviate WCDMA-MSC as;
The IMSI number of the SIM card that the user used in the GSM network originally: abbreviate G-IMSI as;
The IMSI number segment at G-IMSI place: abbreviate G-IMSI-AREA as;
Identification number IMSI on the SIM card of using after the user is moved in the WCDMA network: abbreviate W-IMSI as;
The IMSI number segment at W-IMSI place: abbreviate W-IMSI-AREA as;
The phone number that the user uses in the front and back from the GSM network migration to the WCDMA network: abbreviate MSISDN as;
The phone number section at subscriber phone number place: abbreviate MSISDN-AREA as.
In GSM and WCDMA network, can be according to user's IMSI and MSISDN addressing.In all application processes of existing GSM network, these two kinds of addressing systems of a user are carried out addressing all point in the attaching position register at this user place.In addition, in existing GSM network, addressing is undertaken by number segment, rather than carry out at certain Subscriber Number.That is: in existing GSM network, addressing is carried out addressing by G-IMSI-AREA, MSISDN-AREA, and that the IMSI number segment at same user place and Mobile Subscriber International ISDN Number segment addressing arrival is same GSM-HLR.
When the user after the GSM network migration is to the WCDMA network, the user has changed SIM card, becomes migrated users, its IMSI number is revised as W-IMSI, the IMSI number segment at its place is W-IMSI-AREA.Because the SIM card of the WCDMA of W-IMSI-AREA correspondence is used the WCDMA authorizing procedure, must can support by WCDMA-HLR, so need make amendment to the routing addressing of migrated users, make the addressing of W-IMSI-AREA on network point to WCDMA-HLR, and GSM-HLR is still pointed in the addressing of MSISDN-AREA, thereby other user who guarantees the number segment MSISDN-AREA at this user place still is in the GSM network.
Consult shown in Figure 3ly, after the WCDMA network, user's IMSI number W-IMSI and user's phone number MSISDN point to different attaching position registers (HLR) to user of the present invention from the GSM network migration.The MSISDN of migrated users still can be addressed to GSM-HLR, and W-IMSI can be addressed among the WCDMA-HLR, and two HLR physically are not same entities, that is:
GSM-MSC still points to GSM-HLR to the addressing of G-IMSI and MSISDN;
WCDMA-MSC points to WCDMA-HLR to the addressing of W-IMSI;
WCDMA-MSC points to GSM-HLR to the addressing of MSISDN.
OSS OSS does not delete the user data (G-IMSI, MSISDN, business datum) among the GSM HLR in user's transition process, only be to increase user data (W-IMSI, MSISDN, business datum) in WCDMA HLR.The business datum that the user is all arranged in GSM HLR and WCDMA HLR like this.The GSM related service data that only comprise user's existing business among the GSM HLR.Because the compatible gsm service data of WCDMA business datum are so comprise all business datums of user's existing business among the WCDMA HLR.
When user's business datum need change, for example user's increase or minimizing signing service or subscriber arrearage caused operator to shut down processing etc. to this user, and OSS need be made amendment to user data.The concrete operations of revising are as follows:
(1) when revising the data of GSM network and WCDMA Web-compatible, then OSS will be revised the user data among GSM HLR and the WCDMA HLR simultaneously.
(2) when revising the business datum of WCDMA special use, then OSS is only revised the user data among the WCDMA HLR.
The operation that WCDMA HLR and GSM HLR revise business datum is as follows:
(1) WCDMA HLR receives the data modification request of OSS OSS, and the user data after WCDMAHLR will upgrade by the operation of insertion user data is inserted into the mobile services switching centre at the current place of user.
(2) GSM HLR no longer is inserted into these data in the mobile services switching centre at the current place of user by inserting the user data operation if receive after the data modification of OSS OSS.
The user carries out the normal flow process upgraded the position as shown in Figure 4 in the prior art in WCDMA MSC.
Consult shown in Figure 5ly, migrated users carries out the process upgraded the position in WCDMA MSC as follows:
Step 1:WCDMA MSC initiates the location update operations request to WCDMA HLR.
Step 2:WCDMA HLR receives after user's the location update operations, judge this user from the GSM network migration to the WCDMA network, then WCDMA HLR uses the SIM card identification number (i.e. old IMSI number SIM card migration before on) of user in the GSM network, and these two parameters of number vlr-Number of the number msc-Number of the mobile services switching centre in the location update operations of WCDMAMSC initiation and VLR Visitor Location Register are initiated the location update operations request to GSM-HLR.
Step 3:GSM-HLR sends to WCDMA HLR and inserts the user data operation requests.
Step 4:WCDMA HLR does not carry out concrete operations after receiving and inserting the user data operation requests, directly returns response message to GSM-HLR.
Step 5:GSM-HLR receives behind the response message completing place information updating and upgrades the operation requests response message to WCDMA HLR home position.
After step 6:WCDMA HLR receives the response message of GSM-HLR, send insertion user data operation requests to WCDMA MSC.
Step 7:WCDMA MSC finishes and inserts the user data operation and return corresponding response message to WCDMA HLR.
Step 8:WCDMA HLR finishes and receives the updating location information of finishing migrated users behind the response message, and to WCDMA MSC home position renewal operation requests response message, and the mobile services switching centre (being Pre MSC) under migrated users is before renewal is initiated canceling position (CancelLocation) operation requests.
Step 9: migrated users affiliated mobile services switching centre (being Pre MSC) before renewal after receiving the canceling position operation requests is deleted the positional information of migrated users.
Step 10: migrated users affiliated mobile services switching centre (being Pre MSC) before renewal returns canceling position operation requests response message to WCDMA HLR.
From above-mentioned flow process, can find out:
1, in the position updating process, WCDMA HLR simulation MSC/VLR is after GSM HLR initiation location update operations WCDMA HLR receives user's location update operations, judge this user from the GSM network migration to the WCDMA network, then WCDMA HLR uses the old IMSI number of the SIM card of user in the GSM network, and parameter m sc-Number and vlr-Number in the location update operations of WCDMAMSC initiation initiate location update operations to GSM-HLR.
GSM HLR to the network entity of position updating request, is exactly WCDMA HLR according to existing processing procedure in fact, inserts user data operation and home position and upgrades response.
WCDMA-HLR receives insertion user data and the position of GSM-HLR and upgrades after the response, inserts user data and position renewal operation response to WCDMA MSC.
2, GSM HLR no longer sends the CancelLocation operation to Pre MSC:
GSM HLR sends the position that finishes and upgrades after the response according to existing business processing logic, will initiate canceling position CancelLocation operation to the MSC/VLR at renewal place, the last position of user.In the present invention, GSM HLR no longer sends the CancelLocation operation to Pre MSC.
In position that the present invention determines more in the new technological process, for WCDMAMSC is a normal position updating process, all users' business datum all normally is inserted among the WCDMAMSC, and the calling service flow process of migrated users will normally be carried out by the flow process of prior art fully.
Consult Fig. 6, because the routing addressing of the number segment MSISDN-AREA at Subscriber Number MSISDN place does not change, so (SendRoutingInfo) operation that sends routing information that GMSC is sent user's called service request will continue to be addressed among the GSM HLR according to subscriber phone number MSISDN; GSM HLR is according to normal handling, returns to the GMSC response (SendRoutingInfoRes) that sends routing information accordingly; GMSC proceeds call treatment according to SendRoutingInfoRes, and user's called service is able to normal handling.
In the process that migrated users carries out upgrading the position in WCDMA MSC, WCDMA HLR sends to the HLR number (hlrNumber) that mscNumber in the location update operations of GSM HLR and vlrNumber parameter also can be a WCDMA HLR, like this, for GSM HLR, GSM HLR as a MSC/VLR entity, thinks that the user roams to WCDMAHLR on WCDMAHLR.Migrated users is got the flow process of route when called and is consulted shown in Figure 7:
Step 1 is not because the routing addressing of the number segment MSISDN-AREA at Subscriber Number MSISDN place has change, so the SendRoutingInfor operation that GMSC is sent user's called service request will continue to be addressed among the GSM HLR according to subscriber phone number MSISDN;
When step 2 is upgraded owing to the position, WCDMA HLR sends to that the mscNumber of GSM HLR and vlrNumber parameter are actual to be the HLR number (hlrNumber) of WCDMA HLR, so GSMHLR will handle according to existing, get roaming number (ProvideRoamingNumber) operation to WCDMA HLR transmission;
Step 3WCDMA HLR receives the ProvideRoamingNumber operation, will send the ProvideRoamingNumber operation to the mobile services switching centre at the current place of user;
The mobile services switching centre at the current place of step 4 user sends to WCDMA HLR and gets roaming number response (ProvideRoamingNumberRes);
Step 5WCDMA HLR is transmitted to GSM HLR with ProvideRoamingNumberRes;
Step 6GSM HLR is according to the information among the ProvideRoamingNumberRes, and the response SendRoutingInforRes that sends SendRoutingInfo is to GMSC, and GMSC finishes user's called service according to this response.
Also can realize user's called short message service for the short message called route SendRoutingInforForSM that gets with reference to the operation of SendRoutingInfo.
Find out that by above-mentioned in prior art solutions, that user's MSISDN and W-IMSI addressing arrive is same HLR.And user of the present invention from the GSM network migration after the WCDMA network, the MSISDN of migrated users still can be addressed to GSM-HLR, and W-IMSI can be addressed among the WCDMA-HLR, two HLR physically are not same entities.Simultaneously do not need to increase the professional route register of network entity, do not influence the existing networking of GSM network.
